Delayed Egress Systems
Delayed Egress prevents a door from being opened from the egress side (going out), usually for a period of 15 seconds (sometimes 30 seconds). This type of device is often used to prevent theft while maintaining life safety. The system is most commonly comprised of an exit device incorporating delayed egress features or an electromagnetic lock and power supply, one of which would contain delayed egress circuitry. When the device is actuated, the door remains locked on the egress side for 15 seconds and then releases to allow egress.
